g 3 Claims.

Our invention relates to improvements in windows, and particularly to ahinged window and to operating and locking structure therefor.

An object of our invention is to provide a win- ,3 dow which can beinstalled or built into any building or structure, eitherduring erectionor remodelling of the building, and which is adaptable. for use insubstantially any and all places where .a casement window or. slidingsashes, or

. ,J in fact any type of windowmight be used.

" .A further object is to provide a window structure in which the windowsashes will shut tightly to make a waterproof closure, and with whichthe sashes are opened toward the outside and conveniently moved andadjusted to any desired degree of opening by manipulation of controlparts from the inside of the window.

Another object is to provide control and operating structure by whichthe window is adjusted to any desired degree of opening with dispatchthe sash to retain the window in a closed relation.

Yet another object and purpose is to provide operating mechanism thatcan be conveniently installed and which possesses greatstrength andrigidity to hold and support the window sashes and to retain the same inany desired position of adjustment, either opened or closed.

With the above and other objects in view, which will be apparent tothose skilled in the art, our present invention includes and embracescertain novel features of construction and combinations of parts whichwill be hereinafter set forth in connection with the drawing and thenpointed out in the claims.

In the drawing:

Figure 1 is a vertical sectional view through a window structureembodying our invention, substantially along the line of I-I of Fig. 2.

Fig. 2 is a view in elevation taken from the inner side of the windowand with fragmentary parts in section.

Fig. 3 is a horizontal sectional view substantially on line 33 of Fig.2.

Fig. 4 is a view similar to Fig. 3 showing the window sashes closed.

Fig. 5 is a fragmentary sectional view on line 5-5 of Fig. 4.

Fig. 6 is a detail fragmentary sectional view through one edge of thesash on line 6-6 of Fig. 4.

Fig. 7 is a fragmentary broken sectional view on line 1-1 of Fig. 2.

Fig. 8 is a fragmentary detail view in section on line 88 of Fig. 5.

and facility, and which also can be used to lock Figs.9 and 10 arefragmentary views in elevation showing the endof the operating rod.

Fig-11 'is a view similar to Fig. 6 showing a modified construction.

The casing structure, generally indicated at I, 5 canloe fitted in anywindow opening, or the like, in a frame, masonry or other wall orstructure, and-this frame and its associated parts can be made of wood,metal, or any other desired suitable material. It is perhaps preferablethat a 10 channel beprovided, as at 2, around the inner opening of theframe I, and at the top and bottom within the channel suitable guide ortrackways 3 can be mounted. Extending from top to bottom andsubstantially centrally between the sides of the casing l we provide asupporting bar 4 disposed and mounted somewhat after the manner of amullion, but having its outer face terminating in line with the insideof the channel way 2..

The window sashes 5 and 6 are of combined size to fill the openingwithin the frame 1 substantially as this. is defined by the channelportion 2 and the trackways 3, and these two sashes are connectedtogether foldably at their adjacent edges by means of .hinges 1. Thesashes 5 and 6 are provided on their upper and lower edges, and adjacentto their outer corners, with projecting pin portionsfl received in theslots of the guidetracks 3, and preferably provided with rollers9 toreduce friction.

A bearing sleeve II] is fitted through an opening in the supporting bar4 and an operating rod 1 I is mounted therethrough for free endwisesliding movement. This operating rod is provided at one end with anoperating handle l2, and at its other end has a toggle link I3 pivotallymounted. This toggle link is provided at its outer end with a bearingportion l4 adapted to serve as a bearing part of a hinge l 5 by whichthe two sashes 5 and 6 are connected together, and as shown in Fig. 5,the butt pin I6 of the hinge fits through this bearing portion M.

It is perhaps preferable that a drag-spring IT, or other means, beprovided to frictionally engage the rod I I to retain the same againstcasual sliding through the sleeve l0, and as the rod I l is movablethrough this sleeve and through the toggle link l3 has direct connectionwith the hinge l5 at the line of swinging mounting of the two sashes, asthe rod II is pushed out or pulled in the two sashes 5 and 6 will beopened or closed, respectively. When the rod H is pulled in to its fullextent so that the two sashes 5 and 6 are entirely shut, the pivotallyjointed connection with the toggle link I3 is on the inside of thesupporting rail 4 and the rod I I can then be swung down to be dependentbelow the sleeve and substantially parallel with the inner face of thisbar 4. A

5 spring clip I9 is conveniently provided to resiliently receive and toretain the rod I I in this position, and it will of course beappreciated that in this relation of the parts the window sashes arepositively locked and retained against being 10 opened in even theslightest degree.

In Fig. 11, we have shown a modification of the structure illustrated inFig. 6, and here the spindle 8 has a roller 90. thereon provided withball bearings or other suitable antifriction bearing structures.Obviously, many forms and types of roller and antifraction bearingstructures can be provided and employed to give ease and facility ofoperation where heavy or large windows are mounted.

Since the two sashes 5 and 6 open out and close in over the trackways 3,it will be apparent that various forms of cleats, flanges, or othertypes of weather stripping can be employed to insure water and weathertight closing of the windows.

While we have herein shown and described only certain specificembodiments of our invention and have suggested only certain possiblemodifications, it will be understood that many changes can be made inthe form, construction, assembly, in-

s'wingably connecting said window sashes together at their adjacentedges, spindle means at the top and bottom outer edges of each sash 00-operating with the guideways to slidably hold the outer edges of thesashes, a guide sleeve carried by said supporting bar within the openingthereof, and an operating rod fitted slidably through said guide sleeveand consequently through said opening and connected with said sashessubstantially along the line of hinging thereof to be moved endwiseslidably through said sleeve and opening to open and close said windowsashes.

2. A window comprising, a frame having guideways at top and bottom andprovided with a middle supporting rail having an opening extendingsubstantially horizontally therethrough, a pair of window sashescombining to close the opening of the frame, hinge means connecting saidwindow sashes swingably together at their adjacent edges, spindle meansat the top and bottom outer edges of each sash cooperating with theguideways to slidably hold the outer edges of the sashes, a guide sleevecarried by said supporting bar within the opening thereof, an operatingrod fitted slidably through said guide sleeve and connected with saidsashes substantially along the line of hinging thereof to be movedendwise slidably through said sleeve and opening to open and close saidwindow sashes, means to hold said rod frictionally within the sleeve tomaintain adjusted positionings of the sashes and a toggle linkassociated with the operating rod to allow said rod to be swung down onthe inner side of the sleeve and supporting bar to lock and retain thesashes in closed relation.

3. A window comprising, a frame having guideways at the top and thebottom thereof and provided with a middle supporting rail having anopening therethrough near its lower end, a pair of window sashescombining to close the opening of the frame, hinge means swingablyconnecting said window sashes together at their adjacent edges, spindlemeans at the top and the bottom outer edges of each sash cooperatingwith the guideways to slidably hold the outer edges of the sashes, aguide sleeve mounted in the opening of the middle supporting rail insubstantially horizontal relation and in alignment with the swingablymounted edges of the two sashes, a jointed operating rod slidably fittedthrough said sleeve and hingedly connected at its outer end with saidsashes, friction means to resist free sliding movement of the operatingrod through the sleeve, the joint of the operating rod being such thatthe main portion thereof can be swung downwardly when the sashes havebeen drawn to a closed position to thus retain the sashes in this closedposition, and means to engage and retain the swung down end of theoperating rod to hold the same in place.
